Abstract
The utility model discloses a radio-frequency card intelligent pre-charging water meter, which overcomes the shortcomings and flaws caused by a long flow channel of a water meter such as difficult processing, high cost, and low precision. The utility model comprises a meter shell, a radio-frequency control device, a flow channel closing device, a traditional water meter core and a counting device. The shell is formed by a left and a right body through rabbet jointing mutually; the radio-frequency control device and the flow channel closing device are arranged in the left body, and the traditional water meter core and the counting device in the right body. The connection part of the left and right bodies is provided with a gasket. The radio-frequency control device, powered by a battery, comprises a liquid crystal display, a non-contact radio-frequency sensor, and a data processing controller. The flow channel closing device comprises a micro-motor, a reduction mechanism, a valve pole and a valve core. Characterized by convenient processing, high precision, and low cost, the product suits intelligent pre-charging water meter in either new or rebuilt residential communities.
Description
Technical field
The utility model relates to apparatus for metering fluids manufacturing technology field, especially refers to a kind of pre-charges water meter of non-contact type radio-frequency card control.
Background technology
Along with quick, the sound development of Chinese society economy, no matter be the residential quarters of newly building up, or old residential quarters, the metering of tap water by early stage " Stall one table ", is transformed into " Every household has an ammeter ".But the thing followed is the surge of workload of checking meter, and problems such as water rate often are in arrears with by certain customers.For this reason, the someone has invented a kind of pre-charges water meter, efficiently solves check meter fatigue and user of the staff of Running-water Company and is in arrears with the water rate problem." IC-card pre-charges water meter " patent that comparatively typical product such as State Intellectual Property Office on September 29th, 1999 are disclosed, notification number is CN2341125Y, " the radio-frequency card remote-controlled intelligent water meter " patent that on May 8th, 2002 is open, notification number is CN2490556Y and on July 14th, 2004, open, notification number was " the public water meter of radio-frequency card pre-payment " patent of CN2625858Y, and electronics radio frequency control technology has ideally realized and the combining of conventional water meter.But no matter be above-mentioned any water meter product, its water meter matrix still is analogous to and disclosed on May 21st, 2003, notification number is " a kind of pre-charges water meter " utility model patent of CN2551976Y, be provided with the ball valve and the conventional water meter movement two parts device that open and close by Electronic Control in the water meter runner, certainly will cause water meter matrix channel size to increase, cause ball valve inner chamber and dosing machine in-core chamber processing difficulties in the runner, precision is low, cost is high.For this reason, people expect a kind of easy to process, cost is low, precision is high intellectual water meter, and to apply intelligent pre-charges water meter required to satisfy vast residential quarters.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of easy to process, cost is low, precision is high intelligent pre-charges water meter to society, overcome prior art because the long processing difficulties that causes of water meter matrix runner, cost height and low defective and the deficiency of precision, to apply intelligent pre-charges water meter required to satisfy vast residential quarters.
The technical scheme that its technical matters that solves the utility model adopts is: the radio frequency card inteligent type pre-charges water meter comprises watchcase, radio frequency control apparatus, runner headstock gear, conventional water meter movement and counting assembly, and described watchcase is rabbeted mutually by left and right two parts matrix and formed; Headstock gear is located at left matrix in described radio frequency control apparatus and the runner, and described conventional water meter movement and counting assembly are located at right matrix.
The junction root of described left and right matrix is provided with O-ring seal.Described radio frequency control apparatus provides power supply by battery, comprises LCDs, noncontact radio frequency induction device and data processing controller.Described runner headstock gear comprises micromotor, reducing gear, valve rod and spool.
The utility model radio frequency card inteligent type pre-charges water meter product, the monoblock type watchcase of traditional pre-charges water meter changed into being rabbeted mutually by left and right two parts matrix form, both made things convenient for processing, improved dimensional accuracy, reduced again raw-material physical dimension requirement, helped improving the manufacturing work efficiency.The use of this product need not to lay spool and line upkeep as common water meter, and is easy for installation, safeguard simply, and it is required to be suitable for intelligent pre-charges water meters newly-built or the reconstruction residential quarters.
Description of drawings
Fig. 1 is the utility model product structure synoptic diagram.
Embodiment
As shown in Figure 1, the utility model radio frequency card inteligent type pre-charges water meter comprises the watchcase that is joined and formed by left and right two parts matrix 15,22.Described left matrix 15 right-hand members are established annular recess 18, and right matrix 22 left ends are established annular boss 20, become the watchcase of this product after left and right two parts matrix 15,22 is rabbeted mutually.Be to improve sealing property, be provided with O-ring seal 19 at the junction root of left and right matrix 15,22.
As shown in Figure 1, described left matrix 15 tops are provided with radio frequency control apparatus, establish headstock gear in the runner.Described radio frequency control apparatus provides power supply by battery 5, and it comprises LCDs 8, noncontact radio frequency induction device 10 and data processing controller 9; Described headstock gear comprises micromotor 12, reducing gear 6, valve rod 14 and spool 17.And be embedded with wear-resisting circle 16 between runner perisporium that spool 17 joins and spool 17 spheres.Described right matrix 22 tops are provided with the counting assembly 3 of conventional water meter, establish the conventional water meter movement 21 that drives counting assembly 3 in the runner.Described radio frequency control apparatus is contained within the case 1 that is fixed on left and right matrix 15,22, establishes windowpane 7 corresponding to case 1 part of LCDs 8 positions.Described counting assembly 3 is contained within the counting outer cover 2, and transparent glass window 4 is established for the water-meter reading reading in described counting outer cover 2 middle parts.
Continue to narrate in conjunction with the accompanying drawings principle of work of the present utility model below.Right matrix 22 interfaces are connected the running water pipe inlet, left matrix 15 interfaces are connected the running water pipe outlet.Under the normal condition, earlier IC-card is placed top case 1 position of noncontact radio frequency induction device 10, reading by Running-water Company's input in the IC-card is input in the data processing controller 9, micromotor 12 output shafts 11 high-speed rotation, slow down by output gear 13 through reducing gear 6, drive spool 17 through valve rod 14 and rotate, spool 17 through holes are with the runner conducting, tap water flows out from left matrix 15 interfaces behind movement 21.When the advance water rate of data presentation in the data processing controller 9 is not enough, data processing controller 9 output signals, micromotor 12 drives spool 17 and cuts out.
